Throughout history, there have been many different objects and concepts that go back and forth between digital and analog. For analog objects and concepts, we have many different things, such as the original antenna TVs, which used an infinite amount of symbols to transmit images where whereas new TVs are digital as they only use two symbols to represent everything. Current TVs use only 1’s and 0’s, making them digital. Another way of communicating, mostly used during the wars, was telegraphs and Morse code, which again used a limited amount of symbols to convey a message, such as dots and dashes. The abacus is also an early example of digital as a process that processes data through the position of the beads rather than a continuous measure. Some examples of analog would be film for cameras, as they have a continuous grade of darkness on them depending on how much light they are exposed to. These are just a few examples of analog vs digital throughout history.
